华为Atlas200DK环境配置指南(版本20.0.0)
官方参考文档
https://support.huaweicloud.com/usermanual-A200dk_3000/atlas200dk_02_0024.html
务必保证配置时版本(20.0.0)一致!!!
1.配置开发环境(自己电脑)
若不在自己电脑上进行开发可以略过这个步骤，例如通过vscode进行远程开发，好用！
1.1.利用脚本快速配置
https://gitee.com/ascend/tools/tree/master/faster_install/for_1.7x.0.0
选择20.0版本
2.配置Atlas200DK
2.1.制作SD卡
一定要按照说明用root用户创建文件夹并且用cp拷贝需要的文件进去！！！！
不知道root密码的可以用下面命令重设
sudo passwd root
https://support.huaweicloud.com/usermanual-A200dk_3000/atlas200dk_02_0011.html
1.0.12.alpha版本： https://support.huaweicloud.com/environment-deployment-Atlas200DK1012/atlased_04_0010.html
c++环境准备和依赖安装
https://gitee.com/ascend/samples/tree/master/cplusplus/environment
缺失acl.h
https://bbs.huaweicloud.com/forum/thread-127320-1-1.html
export DDK_PATH=$HOME/Ascend/ascend-toolkit/latest/arm64-linux_gcc7.3.0
重新执行
cmake ../../../src -DCMAKE_CXX_COMPILER=aarch64-linux-gnu-g++ -DCMAKE_SKIP_RPATH=TRUE
可以写入.zshrc
1.0.12版本为：export DDK_PATH=$HOME/Ascend/ascend-toolkit/latest/arm64-linux
2.2.连接开发版
2.2.1.查看USB虚拟网卡
当通过USB线连接到虚拟机上后，执行以下命令可以查看到虚拟网卡。
ifconfig
enp0s20f0u1: flags=4163<UP,BROADCAST,RUNNING,MULTICAST> mtu 1500
inet6 fe80::129b:4364:6360:ca75 prefixlen 64 scopeid 0x20<link>
ether 7a:76:dc:7e:c2:27 txqueuelen 1000 (Ethernet)
RX packets 8 bytes 803 (803.0 B)
RX errors 0 dropped 0 overruns 0 frame 0
TX packets 16 bytes 3148 (3.1 KB)
TX errors 0 dropped 0 overruns 0 carrier 0 collisions 0
其中enp0s20f0u1就是虚拟网卡。
2.2.2.配置虚拟网卡ip
由于通过USB连接时，开发板默认IP为192.168.1.2，所以这里我们只需要配置虚拟网卡ip为192.168.1.x即可。可按照如下命令进行netplan设置。
切换为root用户，并安装VIM。
su root
apt-get install vim
打开netplan的配置文件，按照以下格式进行配置填写。
vim /etc/netplan/01-network-manager-all.yaml
# Let NetworkManager manage all devices on this system
network:
version: 2
renderer: NetworkManager
ethernets:
enp0s20f0u1: #配置的网卡名称,使用ifconfig -a查看得到
dhcp4: no #dhcp4关闭
addresses: [192.168.1.223/8] #设置本机IP及掩码
gateway4: 255.255.255.0 #设置网关
nameservers:
addresses: [114.114.114.114]
注1：要注意缩进，netplan内容和python一样，对缩进有严格要求，如果缩进格式不对，则配置会失败。
注2：这里的配置网卡名称，需要根据自己连接的情况看，不一定是enp0s20f0u1。
配置完成后执行以下命令，使配置生效。
netplan apply
执行以下命令切换回普通用户。
exit
如下图所示，再使用ifconfig查看，此时已经有ip了。
enp0s20f0u1: flags=4163<UP,BROADCAST,RUNNING,MULTICAST> mtu 1500
inet 192.168.1.223 netmask 255.0.0.0 broadcast 192.255.255.255
inet6 fe80::7876:dcff:fe7e:c227 prefixlen 64 scopeid 0x20<link>
ether 7a:76:dc:7e:c2:27 txqueuelen 1000 (Ethernet)
RX packets 14 bytes 1241 (1.2 KB)
RX errors 0 dropped 0 overruns 0 frame 0
TX packets 183 bytes 39769 (39.7 KB)
TX errors 0 dropped 0 overruns 0 carrier 0 collisions 0
2.2.3.登录开发板
在普通用户下通过ssh指令，登录开发板（密码为Mind@123）。
ssh [email protected]
2.2.4.将动态链接库路径添加到开发板的 ldconfig 文件中
切换到root用户下搜索 libascendcl.so 所在的路径：
su root
find / -name libascendcl.so
路径如下
/home/HwHiAiUser/Ascend/acllib/lib64/libascendcl.so
打开ld.so.conf.d文件
vim /etc/ld.so.conf.d/mind_so.conf
添加路径到此文件中
/usr/lib64
/home/HwHiAiUser/Ascend/acllib/lib64/
添加完成后，执行 ldconfig
执行以下命令，退出开发板。
exit
exit
3.验证配置是否成功
参考如下博文的例子进行验证
https://gitee.com/ascend/samples/tree/master/cplusplus/level2_simple_inference/2_object_detection/YOLOV3_coco_detection_video
4.额外配置可选
4.1.配置远程登录桌面
https://bbs.huaweicloud.com/forum/thread-29830-1-1.html
可能出现的问题
执行sudo systemctl restart xrdp,报错如下
A dependency job for xrdp.service failed. see journalctl -xe for details
- 执行命令
sudo rm /lib/systemd/system/xrdp.service /lib/systemd/system/xrdp-sesman.service - 重启设备
- 执行
sudo systemctl status xrdp检查是否运行成功如下
参考:https://c-nergy.be/blog/?p=8316
4.2.通过网线连接开发版
4.2.1.查看网口网卡
当通过网线连接到虚拟机上后，执行以下命令可以查看到网卡。
ifconfig
eno1: flags=4099<UP,BROADCAST,MULTICAST> mtu 1500
ether 3c:52:82:e4:93:ef txqueuelen 1000 (Ethernet)
RX packets 0 bytes 0 (0.0 B)
RX errors 0 dropped 0 overruns 0 frame 0
TX packets 0 bytes 0 (0.0 B)
TX errors 0 dropped 0 overruns 0 carrier 0 collisions 0
其中eno1就是网卡。
4.2.2.配置开发环境端网卡IP
前面配置的USB虚拟网卡的IP为192.168.1.2，不应与改IP冲突，因此设置网线网卡的IP为192.168.2.2
按照如下命令进行netplan设置。
打开netplan的配置文件，按照以下格式进行配置填写。
sudo gedit /etc/netplan/01-network-manager-all.yaml
# Let NetworkManager manage all devices on this system
network:
version: 2
renderer: NetworkManager
ethernets:
enp0s20f0u1: #配置的网卡名称,使用ifconfig -a查看得到
dhcp4: no #dhcp4关闭
addresses: [192.168.1.223/8] #设置本机IP及掩码
gateway4: 255.255.255.0 #设置网关
nameservers:
addresses: [114.114.114.114]
eno1: #配置的网卡名称,使用ifconfig -a查看得到
dhcp4: no #dhcp4关闭
addresses: [192.168.2.223/8] #设置本机IP及掩码
gateway4: 255.255.255.0 #设置网关
nameservers:
addresses: [114.114.114.114]
注1：要注意缩进，netplan内容和python一样，对缩进有严格要求，如果缩进格式不对，则配置会失败。
注2：这里的配置网卡名称，需要根据自己连接的情况看，不一定是eno1。
配置完成后执行以下命令，使配置生效。
sudo netplan apply
如下图所示，再使用ifconfig查看，此时已经有ip了。
eno1: flags=4163<UP,BROADCAST,RUNNING,MULTICAST> mtu 1500
inet 192.168.2.223 netmask 255.0.0.0 broadcast 192.255.255.255
inet6 fe80::3e52:82ff:fee4:93ef prefixlen 64 scopeid 0x20<link>
ether 3c:52:82:e4:93:ef txqueuelen 1000 (Ethernet)
RX packets 9 bytes 1065 (1.0 KB)
RX errors 0 dropped 0 overruns 0 frame 0
TX packets 54 bytes 7103 (7.1 KB)
TX errors 0 dropped 0 overruns 0 carrier 0 collisions 0
若显示如，重新拔插一下atlas端的网线即可，正常应该亮绿灯
eno1: flags=4099<UP,BROADCAST,MULTICAST> mtu 1500
ether 3c:52:82:e4:93:ef txqueuelen 1000 (Ethernet)
RX packets 0 bytes 0 (0.0 B)
RX errors 0 dropped 0 overruns 0 frame 0
TX packets 0 bytes 0 (0.0 B)
TX errors 0 dropped 0 overruns 0 carrier 0 collisions 0
4.2.3.配置Atals200DK网线网卡IP
还是先通过USB虚拟网卡连接Atlas200DK
ssh [email protected]
打开netplan的配置文件，按照以下格式进行配置填写。
sudo vim /etc/netplan/01-netcfg.yaml
network:
version: 2
# renderer: NetworkManager
renderer: networkd
ethernets:
eth0:
#dhcp4: yes
dhcp4: no
addresses: [192.168.2.2/24]
gateway4: 255.255.255.0
usb0:
dhcp4: no
addresses: [192.168.1.2/24]
gateway4: 192.168.0.1
配置完成后执行以下命令，使配置生效。
sudo netplan apply
如下图所示，再使用ifconfig查看，此时已经有ip了。
eth0: flags=4163<UP,BROADCAST,RUNNING,MULTICAST> mtu 1500
inet 192.168.2.2 netmask 255.255.255.0 broadcast 192.168.2.255
ether 10:c3:ab:c9:f3:f6 txqueuelen 1000 (Ethernet)
RX packets 107 bytes 12330 (12.3 KB)
RX errors 0 dropped 22 overruns 0 frame 0
TX packets 23 bytes 2514 (2.5 KB)
TX errors 0 dropped 0 overruns 0 carrier 0 collisions 0
device interrupt 69
4.2.4.登录开发板
拔掉USB，在普通用户下通过ssh指令，登录开发板（密码为Mind@123）。
ssh [email protected]
若可以登录则配置成功
以上配置应该会导致网口无法正常联网，若无法联网则注释掉对应netplan里的配置即可
4.3.配置开发环境
https://support.huaweicloud.com/environment-deployment-Atlas200DK1012/atlased_04_0017.html
4.3.1. python 安装
https://support.huaweicloud.com/cann503installguide/install_024.html
4.3.2. 开发包安装
依据
https://support.huaweicloud.com/environment-deployment-Atlas200DK1012/atlased_04_0017.html
5.其他的使用技巧
5.1.更改SD卡分区
https://blog.csdn.net/weixin_41018348/article/details/82592057?utm_medium=distribute.pc_relevant_t0.none-task-blog-BlogCommendFromMachineLearnPai2-1.control&depth_1-utm_source=distribute.pc_relevant_t0.none-task-blog-BlogCommendFromMachineLearnPai2-1.control
5.2.复制文件到开发版
scp $HOME/ascend_ddk/arm/lib/libpresenteragent.so [email protected]:/home/HwHiAiUser
5.2.启用sudo
不需要每次都进root但其实本质一样，不过感觉更好区分一点
su root
vim /etc/sudoers
添加一句
HwHiAiUser ALL=(ALL:ALL) ALL
5.3.连接网络
sudo vim /etc/netplan/01-netcfg.yaml
修改为如下
network:
version: 2
# renderer: NetworkManager
renderer: networkd
ethernets:
eth0:
dhcp4: yes
#addresses: [192.168.0.2/24]
#gateway4: 192.168.0.1
#nameservers:
# addresses: [255.255.0.0]
usb0:
dhcp4: no
addresses: [192.168.1.2/24]
gateway4: 192.168.0.1
保存重启Atlas
5.4.更换为清华源
sudo vim /etc/apt/sources.list
修改如下
#deb http://ports.ubuntu.com/ubuntu-ports/ bionic main
#deb http://ports.ubuntu.com/ubuntu-ports/ bionic-security main
#deb http://ports.ubuntu.com/ubuntu-ports/ bionic-updates main
deb http://mirrors.tuna.tsinghua.edu.cn/ubuntu-ports/ bionic main multiverse restricted universe
deb http://mirrors.tuna.tsinghua.edu.cn/ubuntu-ports/ bionic-security main multiverse restricted universe
deb http://mirrors.tuna.tsinghua.edu.cn/ubuntu-ports/ bionic-updates main multiverse restricted universe
一定所有源（main multiverse restricted universe）都打开，否则安装ros会缺少依赖
5.5.安装ROS
sudo sh -c '. /etc/lsb-release && echo "deb http://mirrors.tuna.tsinghua.edu.cn/ros/ubuntu/ `lsb_release -cs` main" > /etc/apt/sources.list.d/ros-latest.list'
sudo apt install curl # if you haven't already installed curl
curl -s https://raw.githubusercontent.com/ros/rosdistro/master/ros.asc | sudo apt-key add -
sudo apt update
若出现错误
W: GPG error: http://mirrors.tuna.tsinghua.edu.cn/ros/ubuntu bionic Release: The following signatures couldn't be verified because the public key is not available: NO_PUBKEY F42ED6FBAB17C654
E: The repository 'http://mirrors.tuna.tsinghua.edu.cn/ros/ubuntu bionic Release' is not signed.
N: Updating from such a repository can't be done securely, and is therefore disabled by default.
N: See apt-secure(8) manpage for repository creation and user configuration details.
不用管
sudo apt-get install -y gnupg2 # 或 gnupg
sudo apt update
sudo apt install ros-melodic-ros-base
Environment setup
echo "source /opt/ros/melodic/setup.bash" >> ~/.bashrc
source ~/.bashrc
Dependencies for building packages
sudo apt install python-rosdep build-essential
sudo rosdep init
rosdep update
5.6.安装VINS依赖
Ceres-Solver
# CMake
sudo apt-get install cmake
# google-glog + gflags
sudo apt-get install libgoogle-glog-dev libgflags-dev
# BLAS & LAPACK
sudo apt-get install libatlas-base-dev
# Eigen3
sudo apt-get install libeigen3-dev
# SuiteSparse and CXSparse (optional)
sudo apt-get install libsuitesparse-dev
ceres-solver-2.0.0.tar.gz下载链接: https://codeload.github.com/ceres-solver/ceres-solver/tar.gz/refs/tags/2.0.0
tar zxf ceres-solver-2.0.0.tar.gz
cd ceres-solver-2.0.0
mkdir ceres-bin
cd ceres-bin
cmake ..
make -j3
make test
# Optionally install Ceres, it can also be exported using CMake which
# allows Ceres to be used without requiring installation, see the documentation
# for the EXPORT_BUILD_DIR option for more information.
sudo make install
ROS依赖
sudo apt-get install ros-melodic-cv-bridge ros-melodic-tf ros-melodic-message-filters ros-melodic-image-transport ros-melodic-nav-msgs ros-melodic-visualization-msgs
Sophus
git clone https://github.com/strasdat/Sophus.git
cd Sophus
git checkout a621ff #版本回溯
修改sophus/so2.cpp中对应为
SO2::SO2()
{
unit_complex_.real(1.0);
unit_complex_.imag(0.0);
}
继续
mkdir build && cd build && cmake .. && sudo make install
5.7.使用FastGit代替Git
关于 FastGit 的使用，本质上与 git 有关。正常的面向 GitHub 的 clone 命令可能如下：
git clone https://github.com/author/repo
对于使用 FastGit 的情况，我们使用如下命令：
git clone https://hub.fastgit.org/author/repo
正如您所见， FastGit 仅仅是 GitHub 的代理，所以我们仅需要替代远程地址。
当然，您也可以直接修改 git 的配置，完全使用 FastGit 替换指向 GitHub 的链接：
git config --global url."https://hub.fastgit.org/".insteadOf "https://github.com/"
撤回操作：
打开home下的.gitconfig文件，把对应替换代码删除
5.8.增加虚拟内存
有时候编译会显示运存不够，因为默认没有分配swap空间
增加2G虚拟内存
sudo dd if=/dev/zero of=/swap bs=1024 count=2048000
sudo mkswap /swap
sudo swapon /swap
free查看，swap不再为0 编译完成后可以swapoff /swap
永久挂载虚拟内存： https://cloud.tencent.com/developer/article/1835500
例：
sudo swapon --show
NAME TYPE SIZE USED PRIO
/swapfile file 2G 2G -2
/dev/nvme0n1p5 partition 6.8G 3.2G -3
假设新加挂载位置：/dev/nvme0n1p5
sudo echo '/dev/nvme0n1p5 none swap sw 0 0' | sudo tee -a /etc/fstab
5.9.安装zsh
安装ohmyzsh
sh -c "$(wget https://raw.github.com/ohmyzsh/ohmyzsh/master/tools/install.sh -O -)"
在.zshrc文末添加
echo "source /opt/ros/melodic/setup.zsh" >> ~/.zshrc
source ~/.zshrc
安装zsh-autosuggestions
git clone https://github.com/zsh-users/zsh-autosuggestions.git $ZSH_CUSTOM/plugins/zsh-autosuggestions
3.编辑~/.zshrc文件
找到plugins=(git)这一行，然后再添加autosuggestions，最后为：
plugins=(git zsh-autosuggestions)
zsh配置文件
